You asked for it, so ETS delivered! ETS're proud to introduce the first G25-660 turbo kit to the GT-R market. This kit is perfect for a street car looking to make around 1150whp with instant spool and transient response.
The G25-660 is the most advanced small frame turbocharger available on the market. This turbocharger featuring an all new ball bearing CHRA, ultra-high Flow G-Series Compressor Wheel, Evolutionary Aero G-Series Turbine Wheel made from high heat resistance Mar-M Alloy with a 1050 Celsius Rating.
G25-660 - Capable of 1150whp with extremely fast spool.

Large runners - At 630cc per cylinder, the vr38 is 21% per cylinder larger than most 3.0l 6cyl and 2.0l 4cyl. On a cylinder to cylinder basis. To put a small runner on such a large cylinder is like putting a restrictor plate on the engine.
Heat Shields - As the front of the GT-R is Aluminum, an unshielded kit can distort or weaken the front end of the vehicle. Also on the passenger side, the fuel lines must be kept cool for both the obvious fire reasons, but also to avoid tuning issues with a varying fuel density. Also if the fuel is allowed to get too hot, it can cause vapor lock issues at the inlets of very high flow pumps.
Pre-Assembled - Because of the very tight fitment of the R35 engine bay, ETS feel that the alignment of the kit must be perfect. The V-Band connections allow for a multitude of clocking positions, if not clocked perfectly, there could be many in and out attempts for install. This will cost either the shop or the customer excess money. To minimize this confusion, ETS kits come pre-assembled, with all water and oil lines installed. This will be a major labor savings at time of install.
Equal length runners - All cylinders, front to back and side to side have runners of a mean length of 12" =/- .300 This allows for precise tuning, crisper throttle response and less individual cylinder trimming. Also to compliment the 12" length which will work best 6500-8000 rpm, ETS use a moderately angled merge collector so there is a powerful scavenging effect to adjacent cylinders at the collector. This creates less back pressure at the exhaust valves and better overall breathing of the engine.
Waste gates in line with flow - With the very high flow rates of the new billet wheel turbo's, ETS have found the waste gate system must be very efficient, or else boost creep could be induced. As well as keeping run away boost under control, a very efficient waste gate system will allow tuners to start a tune at a much lower boost pressure, ensuring that the whole tuning process is done safely.
Factory Intake, IC pipe positions - Both the intakes and intercooler pipes terminate in factory positions, allowing the turbo kit to bolt up to your existing stock turbo intakes and Intercooler kits.
Down Pipes to factory locations - The High flowing 3" v band downpipes terminate at factory location allowing perfect connection to factory or aftermarket Y pipes. Downpipes are also bracketed to help locate the correct clocking outside the car
Critical Lines Away from heat - All of the Oil/Water lines are routed away from heat, down and around the turbos, instead of over and across the turbos. This will ensure a lifetime service life for these lines, while also lowering the temperatures of the fluids within the lines.
Support Brackets for Critical Lines - All Oil / Water lines are bracketed to prevent vibration or failures. This is extremely important for track vehicles, where high vibration and G forces can cause premature failure of unsupported lines.
Fully ported at every transition - From the head flanges to the exhaust flanges and even the PCV barbs in between, ETS pride ourselves on the best craftsmanship and attention to detail in the industry. This means that all flanges are surfaced, all transitions ported, and all pieces are clean. These details may not make any major power differences, but it can be the difference in numbers such as 998 vs 1002 whp.
Lifetime Warranty - Full Lifetime warranty on all fabricated parts, and manufactures warranty on turbo's.
